ok so as stated above this trophy is gained by Trevor ONLY! 5 rampages, all rather easy, just be careful with the 4th as they come with 2 or 3 tanks..... plus troop trucks..... here is a video regarding the trophy and how to do it. i have not made it! this video was made by PhatSteve7 so all video credits go to him :) hope this helps and good luck :)
